Pin muxing

Table 7

defines the pin list and muxing for this device.

Each entry of Table 7 shows all the possible configurations for each pin, via the alternate

functions. The default function assigned to each pin after reset is indicated by ALT0.

Note:

Pins labeled “NC” are to be left unconnected. Any connection to an external circuit or

voltage may cause unpredictable device behavior or damage.

Pins labeled “Reserved” are to be tied to ground. Not doing so may cause unpredictable

device behavior.

6. RESET output shall be considered valid only after the 3.3V supply reaches its stable value.

None of system pins (except RESET) provides an open drain output.
